对广州地铁三号线沿线临近建筑物的振动响应进行了实测，并结合数值计算研究了地铁振动在建筑结构内的传播规律。研究结果表明：在框架结构中，随着建筑物高度的增加，振动峰值逐渐减小；地铁振动在建筑物内引起的振动时程的频率集中在30～80 Hz频段内，以30～50 Hz频段为主；结构内部构件柱的振动衰减要比周边构件更加显著，柱上的梁越多，能量的损耗就越大；地铁振动引起的加速度值有可能对建筑物中使用人群的舒适度造成影响。

The subway-induced vibration response of the nearby buildings along Guangzhou Metro Line 3 was inves-tigated via site measurement , and the vibration propagation in buildings was numerically analyzed .The results show that (1) in frame structures, the vibration peak decreases with the increase of building height;(2) the subway-in-duced vibration frequency varies from 30 to 80Hz, mainly in the range of 30~50Hz;(3) the vibration reduction of the internal structure column is more significant than that of surrounding columns;(4) more beams on the column may result in greater energy loss;and (5) the acceleration caused by subway vibration may have an impact on the comfort level of people in buildings .
